What Causes Pain In Lower Ribs When I Sneeze Or Cough?

I ve had this pain in the lower right side of my ribs for 4 days now. it s worse than it was the 1st day but about the same as yesterday. I can t exactly tell if it s my ribs or directly underneath. It hurts when i sneeze,cough,stretch,laugh. Hurts to touch it. I don t know if It s serious enough to see a Dr. or to just wait it out and let it go away on its own. Also, I had bronchitis last month. The coughing has almost ceased as of 2 weeks ago. But I still have a cough every now and again daily, but it s not bronchitis. It comes from my throat. I just recently quit smoking about a month ago. So the continued cough could be from that.
